Publication: Lauer, P.; Torralba, A.; Fišer, D.; Höller, D.; Wichlacz, J.; Hoffmann, J. 2021. Polynomial-Time in PDDL Input Size: Making the Delete Relaxation Feasible for Lifted Planning. In Proc. IJCAI-21. benchmarks.zip contains the newly introduced hard to ground benchmarks. hur-source-code.zip contains the standard implementation of h^{ur} and h^{ur-d}. The implementation was done inside the Powerlifted Planner. This means the .zip includes the planners' source code. See references for more details. tiebreak-source-code.zip is a modification of hur-source-code.zip to be used with the tie-breaking variants.
